The National Transportation Safety Board (NTSB) has issued several strong warnings after a few dangerous incidents involving people dancing to one of Drake’s latest songs, “In My Feelings” happened nationwide in the U.S.

Ato Fox 8, Instagram user theshiggyshow popularized the dance challenge after posting his choreographed dance moves to the song online. Some who took the Shiggy challenge however, added some risky elements to the dance, which prompted NTSB to issue the warning.

Many followers of theshiggyshow, whch included celebrities, made their own dance videos for the challenge, and hashtagged it #theshiggychallenge, or #inmyfeelingschallenge. The challenge quickly became viral, but it soon moved to more extreme levels when some people jumped out of moving vehicle, or climbed on a roofs, or stood on moving motorcycles while dancing to the song. Some people were injured as well.

Fox 8 reported about one such challenge-taker, 22-year-old Jaylen Norwood from Florida. He was planning to jump on a car hood and keep dancing, but slipped on an oil slick right before the car hit him. Thankfully he sustained only minor injuries.

Another challenge-taker, Barbara Kopylova, got hurt after hopping out of her car from the driver’s seat. She later posted the video on Twitter and wrote, “I almost died.”

All these mishaps prompted the NTSB to put out a serious warning on its blog for those who might want to impress others by doing the challenge.

“Recently, the #InMyFeelings challenge introduced a new safety challenge to road users. It began with a fan dancing to the Drake song “In My Feelings” and posting a video of his moves. Then, fans began hopping out of cars as they rolled along in neutral to dance to the lyrics “Keke, do you love me? Are you riding?” Often the driver is the one doing the recording. Sometimes the driver was even the one who got out and danced.

“Driver distraction features prominently in this viral challenge, but the more obvious risk is the poor decision to hop out of a moving vehicle to dance. Although “Bad Decision Making” is not on our MWL (Most Wanted List).”

In reminding the challenge-takers that motor vehicle crashes take more than 37,000 American lives each year and that almost all roadway deaths are preventable, NTSB said:

“Avoid becoming—or causing—an #InMyFeelings fatality. All you have to do is not jump out of a moving vehicle. Crashes happen fast, sometimes in the blink of an eye. Driving distracted is dangerous and can be deadly. No call, no text, no update is worth a human life. No dance is either. In my feelings, that’s a pretty simple ask.”
